I came here at about 1:30 PM on a Friday and was pleasantly surprised to wait only 40 minutes ... which should say a lot about establishments like these. The waiting area was crowded and dreary and the receptionists were stressed and overworked. Fortunately, I didn't have to interact with them very much. The phlebotomists were friendly and efficient.
If you come here, be patient and prepared. I feel like I was very lucky to have only a 40 minute wait time as a walk-in, so make an appointment if you can.
